run-zvbc not documented in doc/vector/code-samples/README.md

[nibrunieAtSi5]

In the current version of doc/vector/code-samples/README.md https://github.com/riscv/riscv-crypto/blob/6ec85fbd7a0ac0db132d86f1443ea5c809fd662d/doc/vector/code-samples/README.md, the target run-zvbc is not listed (although it seems to be present in the Makefile (

riscv-crypto/doc/vector/code-samples/Makefile

Line 175 in 6ec85fb

run-zvbc: zvbc-test

)

Moreover the test description is reduced compared to other tests:

• zvbb-test.c - shows proper usage of instructions in the Zvbb extension. The resulting program generates a set of random verification data and applies the Zvbb routines to that.
• zvbc-test.c - shows usage of the Zvbc extensions.

Is it because the code samples have a limited coverage of zvbc compared to other extensions ?
